Latest version 1.17 released in Nov '21 uses Antlr 4.9.1?

[kaby76]

I don't use Intellij ....... IDEA IDE that often (as the file chooser takes 5 minutes to open any file because JetBrains decided to not implement a lazy evaluation file chooser and instead reads my entire 1TB file system to construct a file system tree--JFC), but I decided I needed to use it to reproduce an error in this StackOverflow question. I am using 2021.3 Community IntellijIDEA, and the ANTLR Intellij plugin 1.17.

The Intellij plugin was released in November 2021. It apparently happened in November '21, and it seems appropriate that it should use the latest release of Antlr, version 4.9.3.

When I go to verify the versions in the UI and the version tag in the generated parser/lexer files, I find out these lovelies:

• In the main IDE for Intellij, open the "Settings" box (menu "File -> Settings". In the far LHS panel, select "Plugins". In the middle panel where it says "Type / to see options", type antlr. In the RHS panel, notice that it says: "This plugin is for ANTLR v4 grammars and includes ANTLR 4.9.1".
• When I go to "Generate ANTLR grammar", the generated parser and lexer are indeed marked up with a comment at the top that says 4.9.1 was used to generate the Java source code.
• When I go to "Configure ANTLR...", it opens the "Configure ANTLR Tool 4.9.2 for Simple.g4".

I'm not a QAer, because I believe a developer should actually test his work, but this is just terrible. The Antlr version numbers are inconsistent, and it doesn't even use the latest version of Antlr 4.9.3 released in November '21.

Will be updating to 4.10 soon...thanks!

I guess we should update https://github.com/antlr/intellij-plugin-v4/blob/master/src/main/antlr/org/antlr/intellij/plugin/parser/ANTLRv4Parser.g4 grammar before publishing the plugin to support options for lexer rules.

Also, we have to regenerate lexer and parser with the new version of ANTLR.

Does this look right @KvanTTT ? #524

@KvanTTT There is an example of the danger faced with big refactorings. a method used by the plugin is no longer available in 4.10: targetExists(). Not sure when it was dropped, but I made a simple version and put it into the plug in directly.

Yes, looks good!

Agree, but the plugin is tightly related to ANTLR tool. It was removed once by me. It's possible to restore the method but I'm not sure it makes sense since you've already written a new one.

Yeah, No big deal. it's all working now. I'm a bit nervous about requiring a fairly recent intellij, but maybe I will allow earlier versions and people can just try it to see if it works. no point in forcibly restricting earlier versions.

As of today, versions 2018.x and 2019.x are barely used compared to other more recent versions, according to plugin download stats:

Plugin version	2018.x	2019.x	2020.x	2021 / 2022
1.17 (nov 4)	147	1146	3932	28734
1.18 (apr 19)	n/a	21	102	651 / 1987

Ok, I'm testing it with a minimum of IC-2020.2.1 because that's the version that fixed an OS X Monterey error about a missing Library. But, I'm allowing any build sense 2019.2 in the plugin.xml in case that works for somebody.

@bjansen Now that 4.10.1 is out I'm working on fixing the plug-in
